The species of Aeromonas are major pathogens causing hemorrhagic septicemia disease in aquatic animals and gastroenteritis in humans. The present study is focusing on isolation of Aeromonas species from hemorrhagic septicemia infected freshwater fish Catla catla collected from two districts viz., West Godavari and SPSR Nellore of Andhra Pradesh, India and assessing their threat in terms of antibiotic resistance patterns and Multiple Antibiotic Resistance (MAR) index. A Total of 50 strains of nine Aeromonas species were isolated and characterized by both biochemical and molecular based on 16S rRNA gene. Among 50 strains A. veronii biovar veronii (32%) and A. veronii bv. sobria (20%) were dominant when compared to other Aeromonas spp. Further, the strains were tested for antibiotic resistance against 17 antibiotics. The strains showed 100% resistance to ampicillin, amoxyclav and oxytetracycline. The least resistance showed against ciprofloxacin, gentamycin and amikacin. All the Aeromonas spp. showed MAR and index value ranged from 0.33-0.78, which indicates origination of isolated Aeromonas spp. from high risk sources of contamination. The results revealed that high frequency of Aeromonas spp. in freshwater fish are potential pathogens and threat to public health. [ABSTRACT FROM AUTHOR] |
